Odd. Even when I hated Farscape
, I loved the alien look. It's what eventually got me around to trying the show again. The muppets; the makeup and prosthetics, the weird interior of Moya - all fantastic. It's one of the best looking space opera TV shows around, IMHO. Love the show now; what it's good at it's great at.
Anyway, I don't care for Firefly (or Bebop, while we're on the topic) and was never really a BSG fan of either stripe. So I guess you might like it.
